Do not rely on memory. In 6 months, you or a future owner will need that Cobra 4600 wiring diagram again.
Do NOT use a "standard car stereo ground" for the antenna. The black DC power wire is not the same as RF ground. The antenna mount must have a direct DC path to the vehicle chassis for a proper counterpoise. If your Cobra 4600 gets "hot mic" feedback or motor noise, 90% of the time it’s a poor RF ground, not a power ground. cobra 4600 wiring diagram
